There's nothing kneejerk about it. Using mocap for the Thing would allow for more flexibility on the filmmakers' part, and allow them to accomplish more with the character in action. The Thing looked decent in the first two movies, but I'm going to have to disagree with you on his looking like an Alex Ross painting come to life. In the Ross painting, the Thing looks like he's made of rock (or whatever rock-like substance he is, I can't remember now). In the movies I thought he looked like he was made of rubber. But people see things differently, so I don't see much use in arguing about it.I'm aware of that, of course. Many human beings are involved, including the performer, the character designer, and the animators. I just resist the kneejerk attitude that CGI is always preferable to conventional effects like miniatures or prosthetics. There are things that CGI is good for and things that prosthetics are good for. I see visual effects as an art form, and I've never seen the logic in thinking that one artistic technique should replace another rather than coexisting with it.A real live human being does play the part in motion capture.
